Painless – sometimes massive – bleeding in the last trimester of the pregnancy strongly suggests previa.
Same treatment whether fetus is alive or dead:
- Immediate resuscitation with fluids
- Transfuse one or two units of fresh blood
- Perform ultrasound examination
- Total previa:
- C/S
- Marginal previa:
- Rupture the bulging membranes
- Diminishes traction on the placenta
- Reduces bleeding
- Deliver vaginally
- Rupture the bulging membranes
- Total previa:
When ultrasound is not available
- Bring patient directly to the operating theater
- Prepare for urgent C/S
- Perform gentle speculum examination
- Total previa:
- C/S
- Marginal previa:
- Rupture the bulging membranes
- Diminishes traction on the placenta
- Reduces bleeding
- Deliver vaginally
- Rupture the bulging membranes
- Total previa:
Watch out for signs of DIC (HELLP Syndrome). Transfuse with fresh blood at the slightest suspicion
